Firing mechanism for guns

My invention relates to firing mechanism for guns.

An important object of my invention is to provide means for firing a gun when the butt of such gun is pushed against the shoulder of the user.

A further object of the invention is to provide a convenient and superior way to fire a gun, for snap shooting at moving game, and for trap and skeet shooting.

A further object is to provide means, alternate with the conventional trigger, for firing a gun, which means are particularly useful to persons who have lost fingers, or who are wearing heavy gloves, as when duck hunting in cold weather.

A still further object of the invention is to provide a novel firing mechanism for guns, which is simple, positive in action, and inexpensive to incorporate in the design of certain guns.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a central vertical longitudinal section through the stock of a gun, and illustrating the firing mechanism embodying my invention,

Figure 2 is an end elevation of the butt of the gun, and,

Figure 3 is a transverse section taken on line 3-3 of Figure 1.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral designates an automatic gun, such as is shown in Patent 1,347,756. This gun comprises a stock 5 including the usual small of the stock 6. The stock has a butt plate i. Secured to the small of the stock 6, is a trigger guard 8, enclosing a trigger 9, pivoted at 9. This trigger 9 corresponds to the trigger 63 in Patent 1,347,756. The trigger 9 extends above and below its pivot 9. When the upper end of the trigger is moved forwardly, the gun is fired.

The stock 5 is provided in its butt end with a recess Ill, which also passes through the butt plate 1. This recess is rectangular. Mounted to reciprocate within the recess i0 is a shoulder plunger I2, which is also rectangular. This shoulder plunger is adapted to project rearwardly beyond the butt plate 6. The shoulder plunger I2 has spaced parallel rods l3 and I4 rigidly secured thereto. The rod 13 is slidably mounted in a guide sleeve I 5, held stationary within an opening l6 formed in the stock 5. The rod l3 has a stop I! rigidly secured to its forward end, to engage the sleeve l5 and limit the rearward movement of the shoulder plunger l2. A compressible coil spring [8 is arranged in the forward end of the opening IE, to engage the stop element IT. The rod I4 is slidably mounted in a sleeve I9, held stationary in an opening 20 formed in the stock 5. The rod I 4 has a stop element 2| rigidly secured thereto to engage with the sleeve l9 and limit the outward movement of the shoulder plunger I2. The opening 20 is continued in a reduced portion 22. A ring 23 slidably receives the rod 14 and engages a compressible coil spring 24, engaging the stop element 2|. The opening 22 extends through the small of the stock 6 and receives in its forward end a guide sleeve 25, slidably receiving the rod M.

The forward end of this-rod is arranged to cona tact with the trigger 9 above its pivot, to move the upper end of the trigger forwardly, to fire the gun, when the shoulder plunger I2 is moved forwardly. The upper end of the trigger 9 has been slightly modified for coaction with the rod 14, but the trigger 9 is substantially the trigger shown in Patent 1,347,756.

It is thus seen that when it is desired to fire the gun it is not necessary to pull the lower end of the trigger, but by shifting the stock 5 rear wardly with relation to the'shoulder plunger !2 which is held against movement by engagement with the shoulder, a relative movement is effected between the rod I4 and the trigger 9, and the upper end of the trigger above the pivot 9' is moved forwardly and the gun fired.

The invention is not restricted for use in connection with the gun shown in Patent 1,347,756, but may be used in connection with other guns which are fired when the upper end of the trigger is moved forwardly, such as shown in Patents 1,025,132 and 1,073,588.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to, without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, what I claim is:

1. A gun including a stock and a pivoted trigger extending above and below its pivot, said stock being provided at its butt end with a recess, a reciprocatory shoulder plunger mounted for movement within the recess, a rod connected with the shoulder plunger and extending longitudinally of the stock and having its forward end arranged to move the upper end of the trigger above its pivot forwardly, and yielding means to oppose the movement of the shoulder plunger into the recess.

2. A gun including a stock and a pivoted trigger extending above and below its pivot, said stock having a recess at its butt end and longitudinally extending openings leading into the recess, substantially parallel rods mounted within the longitudinal openings to reciprocate therein, areciprocatory shoulder plunger mounted within the recess and secured to the rods, springs mounted within the openings and serving to shift the rods toward the butt end of the stock, one rod having its forward end terminating ad- REFERENCES CITED The following references are of record in the file of this patent:
